Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is clear. The description adds useful ordering behavior ('newest first') but says nothing about pagination, time range, or permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short and has no filler, but it is a sentence fragment rather than a front-loaded statement of purpose. Its brevity comes at the cost of useful specification.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only tool with one parameter and annotations covering safety, the description provides the core context: ownership changes shown newest first. It is still incomplete because it never mentions the required appId parameter or explicitly states that a list of transfers is returned.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the sole parameter appId is not mentioned in the description. The schema defines it as a required numeric string, but the description does not compensate by explaining what appId means or how it scopes the transfer lookup.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives the subject matter ('when the app moved from one publisher account to another') and ordering ('newest first'), so an agent can infer it returns app transfer history. However, it lacks an explicit verb or resource statement such as 'list app transfers,' and it does not directly distinguish itself from siblings like get_app or get_publisher.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. The implied context is ownership-change history, but the agent must infer that.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
